I'm trying to run my php App on Ubuntu Server 11.10. This App works fine under Apache + PHP in windows. I have other applications that I can simply copy&paste between the 2 OS and they work on both. (These don't use cURL).

However this one uses the php library tonic (RESTful webservices) and makes us of php cURL module. The issue is I'm not getting an error message which makes it impossible to find the issue.

I (must) use NTLM authentication and this is done with AuthenNTLM Apache Module:
